A method includes performing a conversion between a video unit of a video and a bitstream of the video. The bitstream conforms to a format rule. The format rule specifies that a syntax element indicating whether an in-loop filtering operation is performed across slice boundaries is selectively included in the bitstream based on whether or how the video unit is partitioned into slices.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the syntax element is in a picture parameter set.
4. The method of claim 1, wherein the format rule further specifies that information about applicability of a tool to the encoding or decoding is allowed to be indicated in the bitstream at both a video slice level and a video picture level, and wherein the tool is configured to map luma samples to particular values and selectively apply a scaling operation to values of chroma samples.
5. The method of claim 1, wherein performing the encoding or the decoding comprises encoding the video into the bitstream.
6. The method of claim 1, wherein performing the encoding or the decoding comprises decoding the video from the bitstream.
8. The apparatus of claim 7, wherein the syntax element is in a picture parameter set.
11. The non-transitory computer-readable storage medium of claim 10, wherein the syntax element is in a picture parameter set.
14. The method of claim 13, wherein the syntax element is in a picture parameter set.
